Secondary structure of proteins, computer artwork. The secondary structure is the shape taken by the strands of proteins, which are biological polymers of amino acids. The sequence of the amino acids helps to determine the secondary structure. The most common structural elements are the alpha helices (spirals) and beta sheet regions (parallel arrows). The biochemical function of a protein is largely dependent on its large scale structure.
